Retiring InvestHK director general Mike Rowse will release his version of the HarbourFest saga in a tell-all tome by the middle of next year.

'I'm really looking forward to that. Most of the work has already been done,' he said yesterday.

Tentatively titled No Minister, the book is one of two planned by Mr Rowse, who turns 60 on Sunday, and follows a July court ruling that effectively cleared him of wrongdoing in the controversial HK$100 million concert series in 2003.

The book will be the first time Mr Rowse has publicly given his account of the HarbourFest controversy. He retires tomorrow.

The other book he has planned will be an autobiography.

'I don't think the full story has been told yet and that's why one of my books is going to tell it,' Mr Rowse said yesterday.

'I think HarbourFest illustrates a number of important constitutional and administrative points. I don't think those have been focused on at all. I think the immediate concern was that a lynch mob was on the rampage, and they needed someone to hang. And they did.'

A disciplinary panel fined Mr Rowse HK$156,660 and severely reprimanded him over the handling of the HarbourFest concerts.

To help revive the economy after the outbreak of severe acute respiratory syndrome in 2003, the government agreed to underwrite HarbourFest for up to HK$100 million. The American Chamber of Commerce was given the task of putting the event together.

'We then had a choice as a department - we could either abandon AmCham and leave them to take the criticism alone or we could stick with them and deliver. It seemed to me that, since our job was to reach out to the international business community, if we had run away from them and left them on their own, we might as well have closed the department down. So it was conscious decision not to run away. I knew then that we would be subject to a lot of criticism, most of it unjustified,' he said.

Despite the finger-pointing surrounding HarbourFest, Mr Rowse cited his department's work in helping to revive the Sars-hit economy in 2003 as a successful highlight of his 34-year civil service career.
